Heat pumps use the reverse cycle of a refrigeration plant to heat water. It transfers heat from a source, such as air or water, to the water which is to be heated. The heat pump system employs an evaporator, a compressor, a condenser, refrigerant gas (we use R410A which is environmentally friendly and super-efficient), and an expansion valve within a closed circuit.

Compressor compresses R410A gas,

Hot gas passes through heat exchanger, heating water

Warm water flows into storage tank

Cooler water flows into heat exchanger

Gas passes through expansion valve, cooling rapidly

Fan blows outside air over evaporator

Gas passes through evaporator, absorbing heat from outside air

WHAT IS CO-EFFICIENCY OF PERFORMANCE (COP) AND HOW DOES IT AFFECT YOU?

To know the COP capacity of your Heat Pump is an important method to evaluate the quality of the product you choose. The higher the better! It guarantees you more savings on electricity, and shows the quality and performance of the Heat Pump.

The Alliance Heat Pumps are highly efficient and utilise the R410 super-efficient gas, and as a result, have extremely high COP rates.

COP (co-efficiency of performance), is best described as - the change in heat at input, relative to the heat at output.
